The blue usually shows more clearly when placed in front of an orange background (such as orange construction paper).
Yep on orange paper with a non bluish paper is the best way:
Non bluish vs S.357 bluish:

I had put these away when I moved 20 years ago and forgot how to ID them. I just found some that have been there over 40 years. I put them
back and I will sort them later. It was just the other day 1980 LOL.
Thank you for the Info.

Watermarks generally show on these stamps, just hold up to light back side.
